Dios, a brilliant man, leads the Harmonian Army under Bishop Sasarai. He helped the Harmonian Army fight the Republic of Dunan to regain territory in Highland, the Fire Bringer in the early part of the Second Fire Bringer War, and alongside the Fire Bringer against Luc's forces at the end of the Second Fire Bringer War. As the Chief of Staff he is always assisting Bishop Sasarai in public and private, and they are almost always seen together. -
